STUNNED: Binky was overwhelmed when she discovered she was pregnant (Image: E4/WENN)

But that doesn't mean she was overjoyed when those two lines flashed on her pregnancy test.

The Made In Chelsea star has admitted she burst into tears when she discovered she was pregnant with on/off boyfriend Josh 'JP' Patterson's baby.

The 26-year-old told Hello! magazine: "My first reaction when I saw [the positive test], honestly? It was 'S***'.

"My heart stopped. I burst into tears. Josh and I weren't talking at the time and I was really overwhelmed."

Binky – real name Alexandra – and JP split up for the second time at the end of the most recent series of Made In Chelsea, with Josh angry about his girlfriend's flirting with Julius Cowdrey.

They previously split after Binky drunkenly kissed another man on a night out.

However, now that Binky is pregnant, the pair are casually dating again - but aren't going to automatically get back together just because they're becoming parents.

JP said: "Where we're both being very mature is with the fact that you should never get back together just because there's a baby in the picture. It has to be for the right reasons."

They added that neither party is dating anybody else.

Binky is returning to Made In Chelsea and will be filming parts of her pregnancy for the E4 show.

She told pals Louise Thompson, Rosie Fortescue and Stephanie Pratt of her baby joy before the news broke – and now, her best friend Ollie Locke has taken to social media to gush over his likely godchild.

Ollie wrote on Instagram: "After a lifetime of friendship I was entrusted with one of the biggest secrets I ever had a privilege of holding on to! I love you more than anything and will spend the next 100 years doing anything I can to help you both!

"You know all this as some things don't need to be said on social media! But you're going to truly be the most fabulous mummy and I can't wait to meet the little one!"

We're sure this new family unit will be a tad awkward for Ollie, though, as he spent the last series of MIC telling Binky not to get back together with JP. Whoops.
